,Applicatie-nene June 14, 1992. l t. I. ..7 i. T0 all whom ifmaycmtcar'n/V L Be it known-that I; PETER SciiNEIDER,aV citizen of theUnited States, ,and a resident of" Oswego, inthe countyof Oswego, intheState of New York, have inventedne-w and" useful Improvements inLumber-Gluingi Presses, of which the following,ftakenfin connectionwitlhthe accompanyingdrawings, is a full, clear,` and` exact description-'This invention relates'to the manufacture of lumber formed ofboards or,planks united by means of glue. The objectjof` the invention is toprovide simple, inexpensive, andV convenient means for expeditiouslygluing the component partsf of the lumber in the process of manufactur-ring said species ot' lumber in quantities; and to that end the inventionconsists in the novel construction of the gluing-press hereinafterdescribed, and set forth in the claims.1

In the annexed drawings, Figure lis a sidehorizontal transverse sectionori line X X in Fig. l, and Fig. 3 is an', enlarged plan `view of theeccentric employed for applying pressureto one of the longitudinal edgesof the lumber in the process of gluing it.

Similar letters of reference indicate corresponding parts.` i

A represents a platform for supporting the pile of lumber in theprocess, of gluing it. B and C are two posts which are firmly erectedrespectively on the rear andfront portions of said platform and receivebetween them the pile of lumber, (indicated ataca) which in thisinstance is represented in the form of their glued edges abutting.

`In piling the lumber in the glue-press the iirst layer is placed uponslats b b, extendingacross the platform A, and the succeeding layers areseparated from each other by other from becoming gluedlto each otherinthe op# eration ofthe press, ashereinafter described.'

The posts B and C constitute the principal posts of thejgluing-press andare provided with suitable clamping devicesfor applying pressure toopposite edges of the lumber in gluing the boards or component parts'there` of together.` The clamping device of the rear principal post B,I preferably form of an in- .front edges thereof.

Serial No. 111,594. (No model.)

termediate post D, which is mounted on a rod '01, disposedlongitudinally upon the platform .and movable laterally toward and fromthe principal post'B. The intermediate. post D has attached-to it rigidrearwardly-extendingr arms e e c, which pass through perforations n inthe principal post B and are perforated, as at e' r,for the reception ofpinsf, which engageuthe front face of the post B to limit the rearwardmovement of the intermediate post D. The plurality of perforationst't'in the 'arms e allow the post D to be adjusted in its position tobear on the rear edges Vof the lumber while pressure is applied to theAll of the pins fff are attached to a vertical bar g, by means of whichsaid pins can be Withdrawn simultaneously from the arms e e eto allowthe post D to freely move toward the principal postB in the opera--ti'on of relieving the'iumber from pressure at the` end of the gluingprocess. The clamping devices on the front"v principal post C, Ipreferably form of eccentrics h h h, which are `provided with enlargedeyes Z, through which passes the post C, as more clearly shown in Fig. 3ot' the drawings. The said post has affixed to it a spline or tongue f,extending -from the bottom of the post nearly to the upper end thereof.The enlarged eye lof each eccentric `is provided withlnotchesjj, one ofwhichis' caused toengage the spline t by lateral pressure exerted on theeccentricwhen turned to bear on the edge ofthe lumber, as illustrated inFigs. 2 and 3 of the drawings. Said engagement of the spline retains theeccentric in its engagement with the lumber.

Each of the eccentrics is formed with a suitable socket forthe receptionof a lever o, by which to turn it, as aforesaid.

-ln the operation of the described gluingpress the post D is placed andsecured in proper position to allow the lumber to be piled against thefront thereof. Then the first layer of lumber with glue applied to thejoining edges thereof is placed upon the bottom slats b b and thelowermost eccentric h is turned to press against the front edge ofsaid'layer, `while the post'D presses on the rear edge of 'the layer,which pressure causes the glued edges to be closely united. After thefirst layer of lumber is thus clamped in the gluepress the slats c c areplaced across said layer IOO and the second layer a is placed upon saidslats and the second eccentric h is turned to apply pressure to thefront of said second layer Io fare withdrawn from the arms e e by meansof the bar g. This allows the post D to be removed from the glued pileof lumber and the layers a a to be removed in succession from the press.

Having described my invention, what I claim isl l. A lumber-gluing presscomprisinga platform for supporting a pile of lumber, posts on the frontand rear portions of said platform and disposed to receive the lumberbetween them, and clam ping devices sustained adjustably on said postsand disposed to bear on the edges of the lumber piled between the postsas set forth.

2. A lumber-gluing press comprising a platform for supporting a pile oflumber, posts on the front and rear portions of said platform anddisposed to receive the lumber between them, clamping devices on saidposts and disposed to bear on the edges of the lumber, and spacing-slatsadapted to be inserted between the layers of lumber as set forth.

3. A lumber-gluing press consisting of a platform for supporting thelumber, posts erected on said platform and disposed to receive thelumber between them, eccentrics pivotally connected to one of said postsand adjustable to bear on the edges of the lumber, and means for turningsaid eccentrics as set forth.

4. In a lumber-gluing press, the combination with a platform forsupporting a pile of lumber, and a post erected on said platform tosustain the rear edges of the pile of lumber, of a cylindrical posterected on the front portion of the platform and having a splineprojecting from it, eccentrics provided with enlarged eyes receivingthrough them said cylindrical post and notched for engaging the spline,and means for turning said eccentrics to press on the edges of thelumber as set forth and shown.

5. A lumber-gluing press consisting of a platform for supporting a pileof lumber, two principal posts erected on the front and rear portions ofsaid platform, an intermediate post adjustably connected to one of theprincipal posts to bear on the edges of the lumber at one side of thepile, and separate clamping devices connected to the other of saidprincipal posts and disposed to bear on the edges of the lumber at theopposite side of the pile as set forth.

6. A lumber-gluing press consisting of a platform for supporting a pileof lumber, two principal posts erected on the front and rear portions ofsaid platform, an intermediate post adjustably connected to one of theprincipal posts to bear on the edges of the lumber at one side of thepile, separately-operating clamping devices connected to the other ofsaid principal posts and disposed to bear on the edges of the lumber atthe opposite side of the pile, and spacing-slats adapted to beintroduced between thelayers of lumber as set forth.

7. A lumber-gluing press consisting of a platform for supporting a pileof lumber, a principal post erected on the rear portion of said platformand perforated at different parts of its height, a rod disposedlongitudinally and movable laterally upon the platform, a post mountedon said rod, perforated horizontal arms attached to the latter post andpassing through perforations of the principal post, pins insertedremovably in the perforations of said arms, a bar attached to said pinsfor moving them simultaneously, a principal post erected on the frontportion of the platform, clamping devices adj ustably connected to saidfront principal post and disposed to bear on the edges of the lumber,and spacingslats adapted to be introduced between the layers of lumberas set forth.
